Application March 21, 1950, Serial No. 151,007

2 Claims. (Cl. 43-263) This invention relates to artificial bait, and more particularly to means for effecting animation of the same.

An object of the invention is to provide an improved fish lure in which parts thereof representative of the movable parts of an insect or the like may be given movements to simulate actuation of wings.

Another object of the invention is to provide an improved fish lure in which parts thereof are representative of the movable parts of an insect or the like are operated by gas pressure actuated means.

Still another object of the invention is to provide a fish lure of the above type in which the gas under pressure for operating the wing structure is generated in the body of the device.

With these and other objects in view, the invention consists in the construction, arrangement and combination of elements of which it is composed, as will be hereinafter more fully described and claimed.

In the accompanying drawing:

Figure 1 is .a plan view of a fish lure constructed according to the present invention;

Figure 2 is a vertical longitudinal section taken along the line 2-2 of Figure 1;

Figure 3.is a side elevation, partly in section, showing the wing structure in another position; and

Figure 4 is a vertical transverse section taken along the line 4-4 of Figure 1.

Referring to the drawing, the fish lure comprises a hollow body II having a fishhook I2 amxed lengthwise thereof, as shown in Figures 2 and 3. The end of the fishhook opposite to the hook is formed with an eye I3 to provide means by which the device can be connected to a fish line I The end of the body I I adjacent the fishhook I2 is open to provide a filler opening for the body and is provided with a closure cap I5 which is detachably connected to the body by conventional screw-threads I6 formed on said body and said cap, respectively.

The opposite end II of the body II is also open and formed with an inwardly inclined wall I8 having an opening I9 formed therein, said opening being normally closed by a flap valve 20 pivotally mounted at 2I on the end I I and retained in closed position by means of a leaf spring 22.

Upstanding from the exterior of the body I I and arranged lengthwise thereof is a rib 24. The rib 24 is formed on the body a suitable distance to the rear of the end I1, and the forward portion 2 of said rib is undercut, as indicated at 25, to provide an open space beneath a portion of the rib. The forward extremity of the portion of the rib 24 which is free of the body II is formed with a depending lug 26 to provide a depending hook.

A wing structure 21, formed from a sheet of flexible material, has an elongated slot 28 formed lengthwise thereof for receiving the rib 24. The wing structure 21 has wings 29 at the opposite sides thereof, said wings being located in spaced relation to the side wall of the body I I and being connected attheir forward ends to the main body of the structure 21.

Extending rearwardly of the portion of the structure-21 having the slot 28 formed therein is an elongated tailpiece 30 which bears against the body I I in the manner shown in Figures 2 and 3.

Projecting forwardly of the main body of the wing structure 21 and arranged along the longitudinal center line thereof is tongue 3| having a lug 32 depending therefrom and normally mounted in an opening 33 formed in the wall of the body I I to close said opening.

The portion of the body of the wing structure directly underlying the lug 26 of the rib 24 is formed with an opening 34 for receiving said lug.

The construction and arrangement of the parts is such that with the rib 24 disposed within the slot 28 and the lug 32 inserted inthe opening 33 in the manner shown in Figure 2, the wing structure 21 will be retained in position on the body v and will be free to move relative to said body;

In order to impart fluttering and other vibratory movements to the wing structure 21 so as to attract fish to the lure, suitable materials may be deposited within the chamber 35 of the body for producing gases. One material found suitable for such purpose is carbide, indicated at 36, Figure 2. When it is desired to charge the device, the cap I5 is unscrewed from the body II and a desired quantity of carbide 36 placed in chamber 35. Moisture supplied to the carbide will generate gas within th chamber and when the pressure of the gas exceeds a predetermined amount, the lug 32 will be forced outwardly of the opening 33 to position the lug 26 in opening 34. This action tips the wings 29 downwardly.

Due to the manner in which the tongue 3| is uplifted when the pressure of th gas within the chamber 35 acts on the lug 32, the body of the wing structure 21 directly to the rear of the tongue and constituting the tailpiece 30 will be flexed in such a way that the tailpiece is put under tension. Consequently, when the pressure of the gas within chamber 35 decreases a pre- 3 determined amount, the tailpiece 30 functions as a spring to return the tongue 3! to its normal position in which the opening 33 is closed by the lug 32. Thus, it will be noted that th lug 32 constitutes a relief valve which is actuated by a build up of gas pressure within the chamber 35 to open the opening 33 and thereby efiect a reduction in such pressure,

During use of the device in water, the body I I will be 'paitlyisubmergd in the water. Since the flap valve"20is normally held seated" against its seat around the opening [9 by the combined pressures of spring 22 and the gas within the chamber 25, as the pressur of the gas within chamber-=65 drops in the manner heretofore described, the pressure of the water acting on theexposed face of the flap valve 20 swings=said valve= inwardly from its seat, thereby permitting *water' to enter the chamber 35 through opening [9. the meantime the relief valve 32 has been actuated tosclose'xthe dpeningg33, ;as has been described; so ,vthatzgaspressure again builds sip-within chamber 535. iWhen zthe "valyek 20 is in equilibrium, 'the :i sprlngfl actzthereon rtozseat the valve, therebysclos bgzo eningsl 9. ;'l2he carbide {38 :will; then generate; gasv pressure iwithinlthe chamber- 3 5, and v{-tlee cycle scieneration? will be repeated to effect edpe atio 9 1121 w ne stru ture; in; t e. ma n eh retaf rei e b dthe screenin n n'sets fo t it sinventie t n s es fios erm e t is-to1hee tbe snumeru chan s n h esha e, a dr method of attaching the various charts-maybe ees ri dqtmwit o de t n fmm t ess a escapeesthein i nas e nafie c a W cket-i leimedi l-QA nr icom ris ns h b dy; vin sa a le se egineat on z t o a a restrictsfil ili eve i -s a r aids l er; ni
